100g マイクロロードセル

These little inexpensive loadcells are great for measuring small forces. Our lab uses them to measure paw pressure from mice pressing levers. Just be careful not to apply too much force, they deform pretty easily.

These loads cells are extremely cheap and very effective. After calibration, I have been able to get the accuracy down to 10-50 mN from the expected value

perfect

This product is excellent: stable and precise. The price is very good, considering it works very well. Robotshop is a top notch vendor, and is very responsive to emails!
